Patented Oct. 29,1912.

Application filed Karel: 22, 1812.. Serial No. 685,688.

To all whom it may concern:

'Be itknown that I, JOHANN Hanson, a citizen of the United States of America, residing at- New Castle, in the count of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Drop-Seats for Locomotive-Cabs, of which the following is a specification, reference being had therein to the accompanying drawing. I

This invention relates to drop seats for locomotive cabs, and the primary object of my invention is to provide an adjustable drop seat that can be advantageously used by the occupants of a locomotivecab or other small compartment, the seat belng construoted whereby it can be dropped out of the way when the engineer deslres to move about in the cab or operate the reversing bar of the locomotive.

' Another object of this invention is to provide a drop seat that "can be adjusted in height and longitudinally adjusted, whereby the seat can be properly positioned for an engineer to be convenient to the throttle of the locomotive and other devices in order that the locomotive is under the control of an engineer when sitting at a cab window.

With the above and other objects in view,

the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and.

then claimed.

Reference will now be had to the drawing, wherein like numerals denote corresponding parts throughout the several views, in which:

Figure 1 is a front elevation of the'drop seat partly broken away and partly insection, Fig. 2 is a side elevation of the same, Fig. 3 is a cross sectional view of the seat, and Fig. 4 is a plan of a portion of the same.

The reference numeral 1 denotes parallel vertical brackets having the upper and lower ends thereof provided with apertured lugs 2 that are secured by screws 3 or other fastening means to the wall 4 of a, locomotive cab or any suitable support. The brackets 1 have longitudinal slots 5 and the outer edges of said brackets are provided with transverse equally spaced slots 6 forming racks.

Extending through the slots 5 are the reduced ends 7 of a supporting bar 8 that has the upper edge thereof provided withtransverse notches 9. The reduced ends 7 are the medium of the strap 16 provided with stems 10 and movably mounted upon said stems and inclosing the extreme en s of the bar 8 are looking members 11 having side teeth 12 and .bottom teeth 13, saidteeth engagingin the racks formed by the transverse slots 6 of the brackets 1. The locking members 11 are retained in engagement with said brackets by coiled compression springs '14 encircling the stems 10 between said members and nuts 15 mounted upon the outer ends of said stems.-

Adjustably mounted upon the supporting bar8 is a metallic strap 16 provided with a notch member 17 that engages in one of the notches 9. The'strap 16 is made of a resilient material and the rear end 18 thereof engages the wall 4 or the sup ort (if the brackets 1. The forward end of the strap is bent to provide a catch 19 and a handle 20, said catch engaging the under side of the supporting bar 8 and retaining the notch member 17 in the notch 9. By in the handle 20 and moving the 1 9 out of engagementwith the under side of the supportln bar 8, the strap 16 can be elevated and shifted to place the either one of the notches 9. I

The strap 16 is provided with barrels 21 and pivotally connected to said barrels by a pin 22 are apertured lugs 23 carried by the notch member 17 in rear edges of a seat 24. The bottom side of the seat 24:, at the front edge thereof, is provided with a depending bearing 25 and pivotally mounted in said bearing by a ,pin 26is the head 27 of a tubular or telescopic leg section 28 in which is slidably mounted a solid leg section 29. The solid leg section is adjustably held in the tubular leg section 28 by a set screw 30.

It is through the medium of the adjust-able telescopic pivoted leg of the seat 24 and the locking members 11 of the supporting bar 8 that the seat 24 can be adjusted in height relatively to a floor, audit is through that the seat can be adjusted longitudinally relatively to the supporting bar 8. When the seat is notin use, the seat-24 is swung to a vertical position with the telescopic leg approximately in parallelism therewith. v

It is thought that the operation and utility and the manner of assembling the parts of the seat will be apparent without further is illustrated a preferred embodiment of the description, and while in the drawing there invention, it is to be understood that the H thereof pivotally connected to said strap,

and a telescopic pivoted leg carried by the forward edge of said seat.

. 2. A dropseat for the cabs of locomotives, comprising slotted brackets, a supporting bar having the ends thereof extending through said brackets and adjustably connected thereto, a strap adjustably mounted upon said supporting bar, a seat having the rear edge thereof pivotally connectedto said strap, and a telescopic leg pivotally supported by said seat.

3. .A drop seat for locomotive cabs, comprising slotted brackets, a supporting bar having the ends thereof extending through sai d bxackets, spring pressed lockmg members arranged upon the ends bf said bar for engaging said brackets and locking said bar relatively to said brackets, a strap adjustably mounted upon said supporting bar, a seat having the: rear edge thereof pivotally connected to said strap, and a leg pivotally supported upon the forward edge of said seat;

4. A drop seat for locomotive cabs comprising parallel slotted racks, a notched supporting bar having the ends thereof extending through said racks, spring pressed looking members movably arranged upon the ends of said bars for engaging said racks, a

strap movably mounted upon said supporting bar, a notch member carried by said strap for engaging in one of the notches of said bar, a seat having the rear edge thereof pivotally connected to said strap, and a telescopic leg pivotally connected to the forward edge .of said seat.

In testimony whereof I aflix my slgnature in the presence of two wltnesses.
